Are linear tracking arms better than pivoted arms?

02-25-10: Dertonarm
We need to eliminate the progression from the stylus.
This can be done, but will be really expensive, as it can not deal with linear progression, but need to be in short-time-loop with the real groove-spacing of the LP on the platter...Once this is done, the full theoretical advantage of the linear tonearm will be obtained.

What still will be an issue after that problem is eliminated, remains the less than perfect stiffness and hardness of the bearing.

Technically, there are several readily-available solutions used in other industries that make these tracking/error/stiffness concerns a non-issue. Atmasphere has discussed them before in other threads. Surprisingly, he suggested the same components that I had decided on, myself.

The real work is in the control system for the mechanisms.

Mepearson, I forgot to put a smiley face (;-))at the end of my sentence saying you gave up too early. I did realize that you wanted to try out what you said top notch pivot arms. That IS indeed open minded. In fact, I have plans to install another arm (Triplanar, most likely) with hopefully same cartridge in near future to just expand my horizons- so to speak.

Thanks to 213cobra for better describing sound quality reproduced by linear arm. "....snapped everything into sonic focus that you didn't realize was available until you heard it." " ..also present the 3D soundspace more vividly". What I would like to add further s that organic quality of acoustic space it portrays to make the whole stage as one- one instrument space clearly overlapping each other to make one whole stage, and more sound air propulsing out as a live instrument would. You can 'peak or hear' in the middle of the tone 'thickness' to hear what texture is in between- if it makes any sense. I guess I described it earlier as 'completeness - tone, texture, air lower and higher harmonics - of notes'. It is still hard to describe until you hear it, but may be I described it succinctly enough? Not that pivotal arms don't do this, they do, sure, but linear arm does convincingly more.

Pivotal arms just looks great, they are in vogue and are just more impressive to possess. Wish list- Triplanar, Graham Phantom, Davinci Grandezza, SME V

>>Has anyone compared recent linear and pivot tonearms on a 2-arm TT at the same time w/ the same cartridge for an A/B comparison? What did you notice?<<

Yes, we did as follows:
Basically in the same system, except the TTs, Scheu Das Laufwerk I with Cartridge Man Conductor II(w/Isolator) and Acoustic Solid Wood Ref with Ortofon AS-212. The cartridge used was an Air-Tight PC-1. Music: classical, jazz, vocals and other instrumental. We played all records once in Acoustic Solid/Ortofon combo(alias: AA combo) and then removed PC-1 and mounted it on Cartridge Man arm on Scheu/Cartridge Man(alias: Scheu combo), and played all the passages again.

In short, the same PC-1 sounded rather different on both setups. Scheu combo, whatever we fine-tuned, would deliver a more relaxed feel as a whole, laid back, a little bit more spacious, violin sounding stunningly "airy" and "real", not thin-sounding, etc.

With AA combo, the soundstage was a tad different, imaging became more solid(a positive term, here), bass tighter and more extended with more weight(but not booming), less laid back, as a whole rather transparent but not that "stunningly airy". Playing pipe organ, AA combo could deliver, what we call, real bass authority!

We did tried another cart, Dynavector Te Kaitora II. A very airy cart and extended at the top but could be a bit thin-sounding, rather "light-weighted" presentations, without much bass authority, extremely relaxed mid-range,...overall sonic results were not as satisifactory as the above, though.

We found the same cart could sound differently with the pivoted and air-bearing linear arms we used. Some of us thought AA combo was closer to recordings without less character of its own. However, some of us preferred Scheu combo which could just sound better to their tastes.

Amendment: I did try another cart, Dyna Te Kaitora II, with Conductor II air-bearing arm...sorry for the mistake.

Hi Danwkw,

Correct me if I'm wrong, but you tried the same cart on two different tables and arms, but never on the same table with both arms?

So, your test was PC-1/Conductor/Das Laufwerk, then PC-1/Ortofon AS-212/Acoustic Solid Wood?

But never PC-1/Conductor/Das Laufwerk, then PC-1/Ortofon AS-212/Das Laufwerk or PC-1/Ortofon AS-212/Acoustic Solid Wood, then PC-1/Conductor/Acoustic Solid Wood?

That's two completely different turntable designs of completely different materials (Scheu's delrin/acrylic vs Acoustic Solid's wood/aluminum).

How do you separate out the the influence of the turntable from that of the tonearms in that test?

BTW, I own a Scheu Premier MK2 w/ the upgraded 80mm platter and their flagship Tacco tonearm AND the Cartridge Man Conductor linear-air bearing arm. Unfortunately, the Premier I own is not a 2-arm version, so I can't do both at the same time.

I wish I could, then I'd just get another Denon DL-103D and see for myself, or a couple of Music Makers.
